This invention relates to improvements in coin controlled lock mechanism.

The principal object of the invention is to produce a locking arrangement which is operated through the medium oi a coin after which the device to which the lock is attached may be actuated.

A further object is to provide means whereby it will be impossible for the lock to be actuated twice with the same coin.

A still further object is to produce a device which is simple in construction and therefore easy to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure I is a vertical cross section of my device as the same would appear when attached to a door, and

Figure 11 is a knob for actuating my device instead of a key.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a door to which a barrel casing 6 is attached. Within this casing is positioned a rotatable barrel 7 having a plurality of tumblers 8 which are adapted to be actuated by a key 9. The construction thus far forms no part of my invention and therefore is merely incidental to the showing, as the tumblers are of the same construction as shown in my co-pending application.

Sufiicient room is provided above the tumblers to house a pivoted lever 11 which is fulcrumed as at 12 and is provided with a counter-weight 13 to which a downturned end 14 is attached which enters a recess 16 formed in the key 9. A downturned end 17 approaches but is spaced from the end of the key 9. An extension 18 is formed on the lever 11 and extends into the coin slot 19 which extends through the door 5. Any form of coin receiving receptacle may be employed as for instance the drawer as shown at 21. is

The result of this construction is that when thecoin is placed in the slot 19 it will fall upon the extension 18 which will drop a short distance or until the arm 17 engages the key 9 at which time the arm 14 is raised out of the recess 16 and consequently the key can be withdrawn. As soon as the end of the key passes outward from under the arm 17 the coin upon the extension 18 will drop into the box 21 and the counter-weight 13 will return. the parts to normal position. When the key is reinserted the lock can be unlocked for the purpose of entering but the key cannot. again be removed until a coin is placed within the coin slot. Locks of this type are employed in stations where lockers are available for the convenience of travelcrs. If desired thekey 9 may be eliminated and a rotatable handle 22 may be substituted therefore, in which event the arm 14 will extend into the opening 23 of the handle and the arm 17 will strike upon the Hat portion 24 of the handle. As soon, however, as a coin is dropped in the coin receptacle and the arm 14 has been withdrawn from the opening 23, the handle maybe given a rotation and as soon as this happens the arm 17 will drop oil the cam surface 26 and permit the coin to pass into the drawer 21.

It will thus be seen that I have produced a device which may be used wherever it is desired to derive a revenue from the use of a locked receptacle, room or like place.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim 1. In a locking mechanism of the character described, the combination of a removable key member, means for locking said key member, said means comprising a pivoted lever, arms formed on said lever, one of said arms engaging a recess formed in said key member, the other of said arms being in alignment with said key member whereby said second arm Will engage said key when said lever is moved, an extension secured to said pivoted member and adapted to receive a coin thereon for the purpose of moving said arm out ofsaid recess in said key member.

2. A coin controlled locking mechanism comprising a removable key member having a recess formed therein and a cam formed adjacent the end thereof, of a pivoted member having a pair of arms adapted to engage said recess and said cam, means for actuating said lever through the engagement of a coin therewith in the manner described.
